L78M00 series

Figure 16. Fixed output regulator

Typical performance

1. To specify an output voltage, substitute voltage value for "XX".

2. Although no output capacitor is need for stability, it does improve transient response.

3. Required if regulator is locate an appreciable distance from power supply filter.

Figure 17. Constant current regulator

IO = VXX/R1+Id

Figure 18. Circuit for increasing output voltage

IR1 ≥ 5 Id

VO = VXX(1+R2/R1)+IdR2
